BACKGROUND OF THE INVENTION 1. Field of the Invention

This invention relates to elongated rods made of combustible plant material for smoking, manufacturing tools used to make the elongated rods, and a method of manufacturing individual elongated rods using the manufacturing tools.

2. Description of the Related Art

It is common for cigarette smokers to roll individual cigarettes using a cigarette rolling machine. A typical cigarette rolling machine includes two parallel rollers aligned horizontally that are mounted at their opposite ends to a rigid frame. The ends of each roller are inserted into slots formed in the rigid frame that enable the spacing between the two rollers to automatically adjust or enable the user to change the spacing between the two rollers.

Wrapped around and extending between the two rollers is a single thin panel. The panel includes an excess, slack region that forms a flexible, U-shaped filling region between the two rollers. During use, the user forces the two rollers apart and deposits small tobacco particles evenly along the entire length of the filling region. The two rollers are then forced together and simultaneously rotated in the same direction. When the two rollers are forced together, the filling region on the thin panel forms a tube that contains the tobacco particles. As the two rollers are then rotated, the tobacco particles are forced inward to create an elongated rod of tobacco. The edge of a piece of rice paper is then inserted into the slot formed between the two rollers and the two rollers are then rotated again to wrap the rice paper around the elongated rod of tobacco. The opposite free edges of the rice paper are licked and twisted to form a cigarette. The two rollers are then separated, and the cigarette is then removed from the rolling machine.

One drawback with cigarette rolling machines described above is that the two rollers and the thin panel exerts pressure on the tobacco particles laterally and not axially. The rice paper must be used to hold the cigarette in an elongated rod configuration.

Cannabis is a genus of flowering plants in the Cannabacae family which consists of three primary species: Cannabis sativa; Cannabis indica; and Cannabis ruderalis. Today, the terms ‘hemp’ or ‘industrial hemp’ refer to species of cannabis that have less than 0.3% THC, (dry weight) and the term ‘marijuana’ is refers to species of cannabis that contains 0.3% or more THC (dry weight). Today, hemp or hemp derived products that contain no more than 0.3% THC are legal under U.S. federal laws and regulations. Cannabis or cannabis derived products containing more that 0.3% THC (also called marijuana) are not currently legal under federal laws and regulations.

What is needed is an elongated rod made of tightly compacted particles of legalized cannabis or other types of plant material, such as tobacco. What is also needed is a manufacturing tool that can make the elongated rods made of compact plant material with at least one optional, longitudinally aligned air conduit formed in the elongated rod. What is also needed is a convenient method of manufacturing an elongated rod made of compacted plant material. using the manufacturing tool.

SUMMARY OF THE INVENTION

Disclosed herein is an elongated rod made of plant material tightly packed together with a relatively high pressure to form and self-contained elongated structure. In one embodiment, the plant material is cut or crushed into small particles (the term ‘small’ is defined as 1/32- 6/32 in inches in width and length and 1/32 to ⅛ inch thick) and packed to form an elongated rod that retains its shape and does not require an outer paper. Because the plant particles are small and tightly compacted, the longitudinal and transverse axial flow of air through the elongated rod may be impeded. In another embodiment, large particles (greater than ⅛ inch thick) may be used with the application of greater pressure. Because the plant material is tightly packed at least one longitudinally aligned air conduit may be formed in the elongated rod when intended to be smoked by the user.

Several tools for manufacturing the elongated rod made of compacted plant material are disclosed. Each tool includes a rod mold with at least one rod cavity formed therein. The rod mold may be a solid block made of rigid material with a straight rod cavity formed in the therein. The rod cavity includes an upper entrance opening and a lower exit opening. The rod cavity may be round, oval, square, rectangular or triangular in cross-section.

In one embodiment of the tool, a stop plate is placed inside the rod cavity configured to cover the exit opening. The stop plate includes a perpendicularly aligned, narrow pin that extends longitudinally inside the rod cavity. The length of the pin is slightly greater than the length of the rod cavity.

Each tool also includes a plunger assembly configured to be inserted into the entrance opening of the rod cavity and applies an axially directed force to pack the plant material inside the rod cavity. The plunger when used with a stop plate with a perpendicularly aligned pin, the plunger must include a pin opening that receives the pin when the plunger is forced downward in the rod cavity.

During use, the stop plate is first placed inside the rod cavity that covers the exit opening. Small particles of plant material are then deposited inside the rod cavity and around the pin. The plunger is then aligned over the rod cavity and the bottom end of the plunger is forced downward against the top surface of the plant material. The rod mold is placed on a flat support surface that supports the stop plate inside the rod cavity. After the elongated rod is formed, the support surface is removed thereby allowing the stop plate to be pushed through the exit opening and removed from the rod cavity. Enough downward pressure is exerted on the plunger so that axially aligned force is applied to the plant material causing the individual small plant particles to be pressed together.

In another embodiment of the tool, the pin is mounted on the end of plunger and extends downward therefrom and configured to slide through a pin opening formed on a sliding stop plate. The pin is sufficiently long so that the pin extends through the pin opening formed on the slide stop plate when the plunger is pulled from the rod cavity. Small particles of plant material may be deposited inside the rod cavity and round the pin. The plunger is forced downward inside the rod cavity to pack the small plant particles. During compaction, the pin slides through the pin opening in the sliding stop plate. After compaction, the sliding stop plate is removed from the tool, thereby enabling the elongated rod to be pushed out through the exit opening on the rod cavity.

With each tool embodiment, the rod cavity may be filled completely with small particles of the same plant material. Alternatively, a plurality of small volumes of plant material are individually deposited and compacted in the rod cavity. After each small volume of plant material is deposited in the rod cavity, the plunger is forced into the rod cavity to compact the plant material. The plunger is then removed from the rod cavity and a second small volume of plant material is placed inside the rod cavity and stacked over the first layer of plant material. The plunger is then reinserted into the rod cavity to compact the second small volume of plant material. The above steps are repeated until the entire rod cavity is filled with individually compacted layers of plant material. Using this method, an elongated rod made of plurality of layers individually compress made from the same or different plant materials, or species. Also, downward force exerted on the layers can vary changing the thickness of each individual layer.

With each tool, the space surrounding the individual plant particles is reduced and air between the particles are forced out of the elongated rod after compaction. The exact pressure applied can be adjusted to control the amount of compaction desired. For example, when making an elongated rod for smoking, the elongated rod may be compressed 25 to 50%. If the elongated rod is intended to be divided into small particles for smoking in a pipe, the air passageway may be eliminated, and the elongated rod may be compressed up to 50-90%.

Both tool embodiments may include compaction percentage markings on the plunger that tell the user the amount of compaction the plant material has undergone to form the compacted elongated rod.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

Referring to the FIGS. there is shown a tool 20 for manufacturing elongated rods 10 made of small particles of plant material 100. The tool 20 may make one standard size rod 10 or it may be easily modified to make different sizes of elongated rods 10, 10′, and 10″ as shown in FIG. 1. Each elongated rod 10′, 10′, 10″ includes at least on longitudinally aligned air conduct 12.

Each elongated rod 10, 10′ and 10″ which is made of compacted particles of plant material, is configured to be smoked or broken into smaller pieces. To make the elongated rods, 10, 10′, 10″, the plant material 100 is cut or crushed into small particles ( 1/32- 6/32 inches) and then tightly compacted to form an elongated rod 10 by applying a force at one end and pressing the plant material longitudinally. The small particles of plant material 100 are so tightly compacted, that the plant particles 100 become pressed together and flow of air through the elongated rod 10, 10′ and 10″ is impeded. The finished elongated rod 10, 10′, 10″ may be a solid structure or it may include one or more longitudinally aligned air conduits 12 that allows the user to inhale smoke through the elongated rod 10, 10′, 10″ when the opposite end is ignited.

In the embodiments, shown herein, the elongated rod 10 is compressing plant material 100 by a special tool 20 designed to compress apply axial force to the small particles of plant material confined by the sides of the rod cavity 40. FIG. 3 shows one embodiment of the tool 20 that includes a rod mold 30 with at least one rod cavity 40 formed. The rod mold 30 may be a solid block made of rigid material with a rod cavity 40 extending through the block. The rod cavity 40 is straight and includes an entrance opening 42 and an exit opening 44. The rod cavity 40 may be round, oval, square, rectangular or triangular in cross-section. In one embodiment, the bottom surface of the rod mold 30 is placed on a planar support base 50 which covers the exit opening 44.

The rod mold 30 shown in FIG. 2 is made of steel or aluminum, cylindrical and contains three elongated rod cavities 40. The three rod cavities 40 are transversely aligned, parallel and evenly spaced apart. It should be understood, the rod mold 30 may be a cube or a parallelogram and is not limited to three rod cavities 40. Greater or fewer numbers of rod cavities 40 may be used.

Disposed inside the rod cavity 40 is a stop plate 60 configured to cover the exit opening 44 As shown in FIGS. 3 and 6A, the stop plate 60 includes a fixed pin 64 perpendicularly aligned on its top surface. The stop plate 60 is a flat, disc-shaped structure configured to be transversely aligned and slide freely inside the rod cavity 40. The pin 64 is axially aligned on the stop plate 60 and configured to extend upward inside the rod cavity 40 when the stop plate 60 is aligned with the exit opening 44. During assembly, the bottom surface 34 of the rod mold 30 is placed on the top surface 52 of the support base 50. The stop plate 60 is then inserted into the rod cavity 40 until the bottom surface of the stop plate 60 rests against the top surface 52 of the support plate 50.

FIG. 6A shows the stop plate 60 with a fixed pin 64. In one embodiment shown in FIG. 6B, the stop plate 60′ uses a replaceable pin 64. The stop plate 60′ includes a threaded bore 61 configured to engage external threads on a replaceable pin 64. The replacement pins 64 may have different diameters thereby enabling the user to make elongated rods with different diameter air conduits.

As shown in FIG. 3, the tool 20 also includes a plunger assembly 70 used to compact the plant material 100 inside the rod cavity 40. The plunger assembly 70 includes an upper plate 72 with at least one perpendicularly aligned plunger 74 configured to slide into the rod cavity 40. The plunger 74 may be a solid or hollow structure. As shown in FIGS. 3 and 5A, formed in the bottom end 75 is a pin opening 76 that forms a passageway for the pin 64 attached to the stop plate 60. The plunger 74 is mounted and perpendicularly aligned on an upper plate 72. In another embodiment, the end of the plunger 74 may be solid, as shown in FIG. 5B. In every embodiment, the width and length of the plunger 74 are sufficient so the bottom end 75 of the plunger 74 forces plant material 100 downward when placed in the rod cavity 40.

The stop plate 60 is placed inside the rod cavity 40 so that it covers the exit opening 44 of the rod cavity 40. Small particles of plant material 100 are manually placed inside the rod cavity 40 over the top surface of the stop plate 60 and around the pin 64. The particles of plant material 100 should be dry and irregularly shaped, 1/16 to ¼ inch in length. The plunger 74 is aligned over the rod cavity 40 so that the pin 64 slides into the pin opening 75. A force generating tool, such as a clamp or press (not shown), is then used to force the plunger 74 into the rod cavity 40 to compact the plant material 100. The force generating tool applies enough axial force on the plunger 74 to compact the plant material 100 ten to fifty percent its original length or depth. Because the rod mold 30, the support plate 50 and the head plate 62 are all made of rigid material, as the plunger 74 is forced downward into the rod cavity 40, lateral forces are also exerted on the small particles of plant material 100 to compact it laterally. By compacting the small particles of plant material 100 ten to fifty percent its original depth or length, the plant material 100 retains its compacted, elongated rod 10 shape after being removed from the rod cavity 40. It should be understood, that the amount compaction desired varies from one user to another. The elongated rod may then be wrapped with rice paper 13 as shown in FIG. 1 to retain the compacted plant material.

After the plunger 74 is forced into the rod cavity 40, the rod mold 30 and the support base 50 are removed. The force generating source is then used to apply a downward force on the plunger assembly 70 to force the stop plate 60 and the elongated rod 10 from the rod cavity 40. After the elongated rod 10 exits the rod cavity 40, the stop plate 60 is then removed from the elongated rod 10. A tightly compacted elongated rod 10 made of plant material 100 is formed with at least one longitudinally aligned air conduit 12.

By controlling the size of the particles of plant material used, the quantity of particles of plant material 100 placed in the rod cavity 40, and the amount of force exerted on the plunger 74, the amount of compaction and the final length of the elongated rod 10 may be controlled. In some instances, one or more conduit may be desirable. In other instances, an air conduit may not be desirable.

As shown in FIG. 7, formed or printed on the outside surface of the plunger 74 are optional compaction percentage markings 79 that tell the user the distance the plunger 74 has been inserted into the rod cavity 40. During use, the user aligns a marking 79 with the top edge of the mold 30. Using this information, the user can estimate the amount of compaction the plant material 100 has undergone to form a compacted elongated rod 10.

As stated above, the stop plate 60 may include a fixed or selectively attachable pin 64, 64′, respectively. The stop plate 60 may also more than one pin 64 thereby enabling the user to form more than one air conduit 12 in a compacted elongated rod 10. For example, FIG. 8 shows an alternative stop plate 160 with three pins 164. FIG. 9 is a top plan view of a stop plate 160 showing the three pins 164 evenly spaced apart in a triangular configuration. Whether or not no pin 64, one pin 64, or several pins are used, depends on how the finished elongated rod 10 will be used (i.e. broken into small pieces or smoked), the size of the particles and the amount of compaction. For example, if the finished elongated rod less than 1 inch in length, or less than ½ inch in diameter, it may not require an air conduit 12. Longer and wider elongated rods 10 or more compacted elongated rods may find two or three air conduits 12 more desirable.

FIG. 10 shows another embodiment of the rod mold 130 (called a split rod mold) made up of two half molds 136,138 that are pivotally connected. The split rod mold 130 enables one mold half 136, 138 to be rotated and separated allowing the compacted elongated rods 10 may be removed laterally from the rod cavities 140.

As shown in FIGS. 11 and 12, show changes to the rod mold and additional accessories that enable the tool to make compacted elongated rods 10, 10′, 10″ with different diameters. FIG. 9 is a partial, sectional, side elevational view of a modified rod cavity 40′ with a sleeve 200 placed inside the original rod cavity 40 shown in FIG. 2 or in a wider, modified rod cavity 40′. The length of the sleeve 200 will extend approximately the entire length of the rod cavity 40 or 40′. The sleeve 200 includes two opposite open ends (only the bottom open end 202 is shown) and a center void area 204. When the stop plate 60 is placed inside the rod cavity 40 or 40′, the sleeve 200 is then placed inside the rod cavity 40, 40′. In the embodiment shown, the end of the sleeve 200 rests against the inside surface of the head plate 62 The pin 64 on the stop plate 60 extends longitudinally in the center void area 204 formed in the sleeve 200.

FIG. 11 shows an insert sleeve 280 placed into the rod cavity 40 that reduces the diameter of the elongated rod 10. A plunger (not shown) compatible with the insert sleeve 280 must be used.

FIG. 12 shows an adapter cover 300 placed over a small diameter plunger 74′. The adapter cover 300 includes a closed end 302 and pin opening 304 formed that is aligned with the air passageway 78′ formed on the plunger 72′. The size of the adapter cover 300 allows it to slide freely into the center void area to compact the plant material deposited.

FIGS. 14A-14E show an alternative method of making an elongated rod of compacted plant material made up of a plurality of small deposits of plant material 302, 304, 306 that are separately deposited into the rod cavity 40 and then compressed with the plunger assembly 70. When completed, a modified elongated rod 500 is made up of a plurality of individual compressed plant layers 502-520—(see FIG. 14F). One advantage when using the alternative method is that each plant layer 502-520 may be made from the same plant species or different plant species. Also, the amount of compression force used to form each plant layer 502-520 may vary.

FIGS. 15A-15E are five sequentially arranged sectional, elevational views of another embodiment of the tool 20 wherein the pin 64 is attached to the end of the plunger 74. In this embodiment, the stop plate 60 described above is replaced by sliding stop plate 65 that moves laterally through slots 77 formed on the sides rod mold 30 that communicate with the rod cavity 40. During use, the sliding stop plate 65 extends transversely over the rod cavity 40 to close the exit opening. After the elongated rod 10 is formed, the slide stop plate 65 is then removed from the rod mold 30 through the slots 77.

FIGS. 16A-16C show three embodiments of the sliding stop plate 65. Each sliding stop plate 65 includes a pin opening 65 (a hole, a slot, or two semi-circular openings that from a pin opening when joined) through which the pin 64 may extend.

The pin 64 is mounted on the closed end of the plunger 74. The pin 64 has a length that exceeds the length of the rod cavity 40 so that the plunger 74 may be raised above the top edge of the rod mold 30 while the tip of the pin 64 extends into the pin opening as shown in FIG. 15A. Small particles of plant material are then deposited into the rod cavity 40.

As shown in FIGS. 15B-C, the plunger 74 is then pressed into the rod cavity 40 to compress the small particles of plant material Once the plant material has been compressed, the plunger 74 is then pulled upward until the tip of the pin by passes the stop plate 65 (see FIG. 15D. The stop plate 65 is then removed from the rod mold 30. The plunger 74 is then forced downward in the rod cavity 40 forcing the elongated rod 10 from the rod cavity 30.

In the embodiments shown herein, the rod cavities 40 are approximately ½ inches diameter and 4 inches in length. The plungers 74 is slightly smaller in diameter and length of the rod cavities 40. The stop plate 60 is approximately 1/32 inch less in diameter than the rod cavity 40 and measures approximately ¼ inch thick. The slide stop plate 65 must be larger in diameter to extend across the rod cavity 40. The pin 64 is approximately 1/16 to ⅛ inch in diameter and 3¾ to 4 inches in length.

FIG. 17 is a graph showing the relation between the final length of the compacted elongated rod 10 formed when a rod cavity 40 that measures 4 inches in length and % inch in diameter that is filled with particles of plant material 100 and compressed with different forces applied to the plunger. When the rod cavity 40 is filled with plant material 100 and 5 to two pounds of force is applied, depending on the particle size of the plant material and the desired amount of compaction. The final elongated rod 10 typically measures 2 to 4 inches in length. In some instances, greater force may be applied 75 to 200 lbs of force, typically applied by a mechanical plunger when the rod cavity 40 is filled with whole or large pieces of plant material. Use of greater force is desirable when greater compaction is desired.

Using the above described tool, a method for making an elongated rod made of plant material is disclosed, comprising the following steps:

selecting a rod mold that includes at least one rod cavity with an entrance opening, an exit opening, a stop plate that fits into the rod cavity and blocks the exit opening, and a sliding plunger configured to be inserted into the rod cavity;

a. inserting the stop plate into the rod cavity near the exit opening;

b. filling the rod cavity with plant material;

c. inserting the plunger into the rod cavity and forcing the plunger against the plant material;

d. applying sufficient force to the plunger to compact the plant material inside the rod cavity and form an elongated rod made of plant material; and

e. removing the elongated rod made of plant material from the rod cavity.

The above method may be modified by using a stop plate with pin perpendicularly aligned that extends longitudinally inside the rod cavity. The above method may also be modified by using a sliding stop plate with a pin opening and attaching a pin on the end of the plunger that extends through the pin opening when the plunger is forced downward in the rod cavity.
